To all whom t may concern.'

Be it known that I, HENRY Hess, a citizen of the United States, residingat Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inPencils, of which the following is a specification, reference being hadtherein t0 the accompanying drawing.

ThisA invention relates to that class of pencils in which the markinglead or crayon is inclosed in a exible sheet such as parchment paper andthe like, wrapped therearound to produce a stiff holding roll or body.In such pencils the inclosing sheet is usually provided with parallelweakened lines, and it is so applied to the lead that these lines willextend diagonally or spirally thereof, whereby the spiral sections orstrips vbetween the weakened lines may be removed successively to exposefresh portions of the lead as it becomes worn down in use. It iscustomary to forni holes in the sheet near its outer edge at intervalscorresponding to the weakened lines, to facilitate the separation of theouter ends of the sections from each other, this separation being eectedby cutting or tearing through the intact portion of the section betweenadjacent holes, by means of a sharp pointed instrument such as a knife,pin or the like.

The aim of my invention is to enable the sections or strips to bereadily unwound, without requiring the use of a tool to start theoperation, and with this end in view my invention consists in a novelformation and construction of the inclosing sheet, as a re'` sult ofwhich the spiral sections or strips between the weakenedv lines willterminate at their outer ends in free lips, over which lips is applied aAlongitudinal protector strip cemented down on the sheet at intervalsbeyond the lips, which strip is adapted to be removed in sections toexpose the respective lips beneath. As a result of this construction andarrangement it will not be necessary to employ a tool or instrument inseparating the spiral sections when they are to be removed, it being butnecessary to grasp the free uncemented portion of the protector stripand tear off a section of the same, which will expose the free lip ofthe section beneath, ywhich lip may be grasped by the iingers, thespiral unwound, and a fresh portion of the marking lead exposed for use.

In the accompanying drawings:

Figure l is an elevation of a pencil having my invention embodiedtherein.

Fig. 2 is a similar view showing a section of the protector stripremoved to expose the free lip of the spiral section which is to beremoved.

Fig. 3 is an elevation of the inclosing wrapper or sheet constructed inaccordance with my invention.

Fig. l is a similar view of the protector strip.

Referring to the drawings:

l represents a marking lead or crayon which in the present instance isin the form of an integral lead or body such as is commonly employed inpencils, although this lead may be other forms well known in this art.The lead is inclosed in a built-up body consisting in the presentinstance of a sheet 2 of fiexible material such as parchment paper orthe like, which sheet is provided with a series of parallel weakenedlines 2 and which sheet is wrapped tightly around the lead in successivecoils, with the weakened lines extending diagonally of the lead andspirally therearound, the outer end of the sheet being cemented down orotherwise fastened to prevent unwinding. In the use of such pencils thespiral sections 2b between the weakened lines are removed in successionto expose fresh portions of the marking lead when the point of thelatter becomes worn down in use, the removal of a section being effectedby first separating its outer end from the adjoining section and thenunwinding and separating it along the weakened line.

In order to enable this operation to be readily performed wholly by thelingers and without the employment of a knife or other implement ortool, I propose, in accordance with my invention, to form the outer endof the sheet in such manner that when the latter is wrapped around thelead to form the inclosing body or roll the spiral sections or stripsbetween the weakened lines will terminate in free lips, which may bereadily grasped between the fingers and the sections unwound andseparated in succession from the adjacent sections. To effect thisobject,-

the sheet near its outer end is formed as shown in Ilig. 3 with allongitudinally eX- tending slot 3, the edges of which are formed withpointed notches 4 at intervals corresponding to the weakened lines 2, Asa result of this construction, the spiral sections or strips between theweakened lines will terminate in lips 5. In winding the sheet on thelead, it is applied to the latter as'shown in Fig. 3 with the weakenedlines extending diagonally of the lead, and when completely wound asshown in Fig. l, the end of the sheet is cemented or otherwise suitablyfastened down to prevent. the same from unwinding. This will leave thelips 5 at the ends of the sections free and ready to be grasped betweenthe fingers. Applied over the lips 5 to protect the same againstaccidental displacement in the use of the pencil, is a longitudinallyextending protector strip 6 which is preferably of paper and of suchform and so applied that it may be removed by the lingers in successivesections to expose the respective lips 5 beneath. This strip in thepresent instance is of the form shown more particularly in Fig. 4, whereit will be seen that its opposite edges are curved outwardly atintervals as at 6, thereby produc-ing a series of sections 6b connectedtogether end to end by reduced necks 6C which are preferably weakened,as by a perforation 6d, to facilitate the separation of one sec-tionfrom the neXt. The sections 6b are of a length corresponding to thewidth of the spiral sections 2b, and in the application of the strip thesections 6b are cemented down on the sections 2b at opposite sides ofthe slot 3 at points beyond the lips 5 as indicated at 7, therebyleaving the lips 5 free and disconnected from the protector strip,

but covered and protected thereby. Along the inner edges of the cementedareas, the sections of the protector strip are formed with weakenedlines such as the perforations 8 to facilitate their separation atthe-se points from the sections 2b.

In the complete pencil shown in Fig. l, the end of the foremost sectionof the protector strip is free and disconnected and constitutes ineffect a lip 9 which when a fresh portion of the lead is to be exposedby the removal of the inclosing spiral section, is grasped between thengers and pulled outwardly. This will cause the uncemented portion ofthe protector section to separate from the cemented portion along theperforations 8, and will cause the end of the section to separate fromthe next at the weakened neck 6c, thereby leaving the end of the neck 6con the next section free. On the removal of the section of the protectoras described, the free lip 5 on the end of the foremost spiral sectionwill be exposed and may be readily grasped between the fingers andunwound from the lead, the spiral secnaeaeoe tion in this operationseparating from the nekt along the intervening weakened line 2a. Thiswill expose a fresh portion of the lead, and will leave the reduced neck6C of the next protector section ready to be grasped in the operation ofremoving the nekt spiral to expose a further portion of the lead.

It will be seen therefore that the removal of the several spiralsections may be performed with facility and wholly by the fingers andwithout the employment of a knife, pin or other implement as hasheretofore been practised.

The protector strip serves in addition to the function described, as ameans of holding that edge of the sheet at the inner limit of the slot 3in place, since the protector strip forms in effect a connection betweenthe outer end of the sheet where it is cemented down in place, and theedge of the sheet at the opposite side of the slot, hence the edge ofthe sheet bearing the lips 5 will be held in place and prevented fromyunwinding without the necessity of cementing this edge down which wouldinterfere with the unwinding of the sections.

In the foregoing description and accompanying drawings I have disclosedmy invention in the detailed form and specific construction which Iprefer to adopt, but 'it will be understood that various changes such aswill suggest themselves to those skilled in the art may be made withoutdeparting from the limits of my invention; and further it will beunderstood that the invention is not limited to any particular form orconstruction of the parts except in so far as such limitations arespecified in the claims.

Having thus described my invention, what I claim is:

l. In a pencil, the combination of a marking lead, a roll ofiiexiblematerial inclosing the same and consisting of separable sectionsadapted to be removed in succession to expose fresh portions of thelead, said sections terminating at their ends in free lips adapted to begrasped in eecting the separation of the sections, and a protectorcovering applied over the lips and adapted to be removed to expose thesame.

2. In a pencil, the combination of a marking lead, a roll of flexiblematerial inclosing the same and consisting of separable sections adaptedto be removed in succession to expose fresh portions of the lead, saidsections terminating at their ends in free lips adapted to be grasped ineecting the separation of the sections, and a protector strip appliedover the lips and adapted to be removed in sections to expose therespective lips.

3. In a pencil, the combination of a mark- 'ing lead, a roll of flexiblematerial inclosing the same and provided with weakened lines to permitthe sections between the lines to be removed, said sections terminatingat their outer ends in lips, and a protector strip consisting ofseparable sections cemented to the first mentioned sections at pointsbeyond the said lips thereby leaving the latter disconnected from theprotector strip; whereby the sections of the protector strip may beremoved to expose the lips beneath.

4. In a pencil, the combination of a marking lead, a roll of liexiblematerial inclosing the same and formed near its outer end with alongitudinally extending slot, the said roll being provided withweakened lines eXtendino from said slot and forming separable sectionsadapted to be removed to expose fresh portions of the lead, and the saidslot being formed with V-shaped recesses coincident with the weakenedlines, whereby the outer ends of the sections will Copies oi this patentmay be obtained for terminate in free lips, and a protector coveringapplied over the lips and being removable in sections to expose therespective lips.

5. ln a pencil, the combination of a marking lead, a roll of flexiblematerial inclosing the same and consisting of separable sections adaptedto be removed in succession to expose fresh portions of the lead, andterminating at their outer ends 1n lips and a protector strip consistingof separable sections applied over the lips and cemented to the firstmentioned sections at points beyond the lips, whereby the latter willremain disconnected and free, the said sections of the protector stripbeing provided with weakened lines at the edges of the cemented areas tofacilitate the separation of the protector sections.

In testimony whereof, I have axed my signature.
